应用激光全息术进行轮胎质量的检验,具有准确、迅速、无损接触、高灵敏度、高精确度等优点。我 们是采用二次曝光法进行轮胎无损检验的,一年多来,取得了较好的结果,现作一简单介绍。 把实验的轮胎置于真空缸中,抽成低压,轮胎即处于第一应力态;用抽气或充气的办法改变真空缸中的真空度,获得第二真空值,轮胎即处于第二应力态。我们知道把轮胎的两种应力态拍摄在同一张全 Application of laser holography tire quality inspection, with accurate, rapid, non-destructive contact, high sensitivity, high accuracy and so on. We are using the second exposure method for tire nondestructive testing, more than a year, achieved good results, make a brief introduction. The experimental tire is placed in a vacuum cylinder, pumping low pressure, the tire is in the first state of stress; with suction or inflation to change the vacuum in the vacuum cylinder to obtain a second vacuum value, the tire is in the second stress state . We know that the tire of the two stress state shot in the same full
